RICHARD L. LONGLEY, OF KANSASI-CIITYIMISSQURI.

' f mDMI-LLQ To all; whom it may concern:

a citizen of the United States,'residing at Kansas City, in the county of J ackson' and State of Missouri, have invented certain new wind-wheel to revent lesssurface to the wind-when the atter is high.

To these ends and others, as v appear, the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter de' scribed and claimed, and in order that it may be fully understoodreference is'to be had to" the accompanying drawings, in which Figure 1 is a frontview of awindniill embodying my invention; 7 Fig. 2 is asection on the line II II of Fig. -1 and. partly broken away; .Fi 3 is a top plan view of a portion of the win mill. Fig. 4 is a vertical section on the dotted line IV. of Fig. 1; v Fig. 5'is an enlarged central longitudinal section of the threaded. shaft and grooved sheave shown in Fig; 4. I

In the said drawings, 1 indicates=,a tower of any suitableor preferred type; 2, a rotatable 'frame 'surmounting and provided with a stem 3, depending intothe upper portion of the tower and suitably journaled therein and provided with a-coll ar-4 below the top of the tower to prevent upward movement of Saidrotatable-frame.

5 represents bearing-caps secured to theupper end ofsaid frame and forming in conjunction. with the latter bearings for the horizontal shaft 6', provided with V I bevel-gear 7, meshing. with bevel-gear 8,. se-

cured on the upper end of'a vertical shaft 9,

7 frame: and its stem? and is adapted to be center of saidbar and provided near itsup which extends down through the rotatable connected with a device or the machinery (not shown) to be operated. 10 indicates a cross bar cast withorsecured to caps 5, and 11 a post rising from the per end with a hole 12 and with a perforated racket 13, the perforation'of the bracket bethreaded and registering with-said, hole, 1

14, equipped with sheave-wheels 1'5. Hinged at 16 to post 11 and projecting upwardly Xtherefrom is a wind-plate 17 limited in its forward movement by the post and connected by a retractile s ring 18 in hole1 2 to an eyebolt 19, swivele in the threaded shaft 20, mounted in the threaded perforation of bracket 13, and. secured ri idly on said threaded shaftis a grooved s nected byan endless cable 22 to a similar sheave 23, journaled on the stub-shaft 24, projecting from the rotatable. frame, 'the sheave-'23 ha a crank-handle 25, whereby v I it may be'turne' to revolve bolt 20, and thus hereinafter increase or diminish the tension of spring 12 'onthewind-plate 17. p

r '26 indicates a pair of cables engaging sheaves '15 and secured at their upper ends,

ends to rock-levers'28, pivotedupon cross- -bar'lO and equipped at their outer ends with the rearwardly-con'vergingbraces 31, b0 ted {at their front ends to said" frame or otherwise suitably securedl outward of the arched trackways 29 are the wind-wheels, constructed as f0 lowsz. 32 indicates cross-shaped frames secured upon pair of frames-at 33 are a series of slats 34 of the type common in window-shutters-that is to say, of that type in which the slats when closed; overlap and occupy parallel positions most clearly inthe-upper part of Fig. 2. Pivoted at 35 to" the arms of the frames are crankshafts 36, and said shafts are provided at theirinnerends with angle-arms 37, pivotally connected to links 38, said links being preferably of angle-iron to insure rigidity and strength and having their inner ends bent, as at 39, and equipped with antifriction-rollers 4Q, retractile springs 41 connecting saidlinks 38 .Withthe arms "of'the'inner frames 32 to hold the antifriction-rollers 40 at their-outer limit of movement from the shaft, and. conas at 27, to the wind-plate and at their lower said shaft, and pivotally connected to each at a slight angle to their supports, as shown eave 21, contatable framethrough the instrumentalit of Secure'd'iipon the opposite ends of shaft 6 I sequently hold said links as close to said arms of the inner frames as possible, as shown most clearly in Fig. .2.

In the practical operationof the machine, assuming that the wind on the vane holds the face of the wind-plate 17 toward the wind without regard to the direction in which the latter is blowing, and consequently holds the wheels with their edges toward the wind; the wind on the wheels causes the latter to revolve in the direction indicated bythe arrow in Fig. 2, in which figure it will be noticed that the slats of the depending arms of the wheel are open, and therefore offer practically no resistance to thewind, while the slats of the upwardly-projectingarms are closed and present an unbroken. front to the wind in ordcr that the pressure of the latter shall revolve the wheel at a high rate of speed, it being also noticed in this com1ection-.-that the arms of the wheels are provided-with jstoppins 42, which limit the openin'gi rnovement of the slats-and prevent them describing a full quarter-revolution. fThefarm's of the wheel projecting toward the win dshow their slats pendent, though in actual practice if the wind be strongenough it may swing them back to folded position by the time they have arrived at the position indicated. The slats carried by the arms projecting away from the wind occupy their folded position by gravity, as at-\ t,hat time there is practically no wind-pressure upon them.- Should the wind increase materially,

in velocity, it will blow the wind-plate 17 more or less in the direction indicated by the arrow, Fig. 4, and thus through the cables 0 erate levers 28 and force the arched tracliways 29 downward and into the path of movement of the rollers 40, which occupy the same vertical plane as said trackways, 'said rollers under normal conditions revolving without contact with said trackway'. When said trackways are lowered, however, as explained, each roller successively engages the trackway and is therefore drawn inward toward the shaft, the springs 41 yielding to ac commodate this movement, which results in pivotal movement of the crank-shafts and causes the same to press outwardly on the pivoted slats and prevent the same from completely closing, the result being the wind is permitted to pass through the wheel between the slats at such times when above theplane of shaft 6. As the wheel is thus deprived of the full power of the wind, its speed decreases.

This regulation'or governing of the wheel is" entirely automatic. Under some'conditions it may be desirable to increase or diminish the tension of the wind-plate, and to do this the operator stretches or relaxes the -spring 18 by screwing shaft 20 outward or'inward "through bracket 13. To accomplish this result, the pulle 23 is rotated for the purpose of turning pul ey 21 through the instrumenwheel, and thus tality of the endless connection" 2 2. As

shown, it is necessary for the operator to.

climb to the top of the tower to accomplish the result described; but I do not wish to limit myself to this particular construction.

From the above description it will be apparent that I have produced a windmill embodying the features of construction enumerated and which may obviously be modified without departing from the principle of construction involved, and while the vane is shown and described as rigid for convenience it will be of course understood that the vane may be of that type in common use whereby it can be turned arallel with the axis of the hold the latter with its side to the wind, and therefore completely out of gear.
